PLUMBING Filed Jan. 27, 1939 INVENTOR 0/4216; P2765 ATTORNEY PatentedOct. 17, 1939 UNITED sTATEs PATENT OFFICE PLUMBING Charles Price, NewYork, N. Y. I Application Jamar, 27, 1939, Serial No. 253,092

l'Claim. (01. 285-115) g This invention relates to plumbing. It isparticularly directed to the connection between a branch lead pipe and asoil stack, and the method of making the same.

I-Ieretofore, lead branch pipes have been connected to soil stacks bymeans of an interconnecting ferrule, ordinarily made of brass or thelike material, and having a flange at one end only, received within thehub of a soil pipe and calked thereto. The lead pipe heretofore has beeninserted into the opposite unflanged end of the ferrule, and a wipedjoint was made by molding or wiping a mass of solder about the junctionof the lead pipe and the cylindrical outer periphery of the ferrule, atthe time of making the installation. The making of the wiped jointrequires special skill and care, in order to produce a strong bondwithout leakage. The making of this joint requires not only experiencebut ability on the part of the plumber.

In modern plumbing practice, wiped joints have been eliminated in manyplaces, and it has been found that plumbers do not get enough experienceand practice in making wiped joints, and for this reason it has oftenbeen difficult to obtain plumbers who are capable of making a reallygood wiped joint, Furthermore, the making of a wiped joint consumesconsiderable time and requires a relatively large amount of solder, andis hence costly as now made. Itis therefore an object of this inventionto provide a connection between the lead branch and the soil stack whichwill save solder and require less time in making the connection, andless skill, and yet produce a strong and durable joint, which shall besmooth, practical and efiicient to a high degree.

Other objects of this invention will in part be obvious and in parthereinafter pointed .out.

The invention accordingly consists in the features of construction,combinations of elements, and arrangement of parts which will beexemplifled in the construction hereinafter described, and of which thescope of application will be indicated in the following claim.

In the accompanying drawing, in which is shown one of the variouspossible illustrative embodiments of this invention:

Fig, 1 is a side elevational view illustrating a connection between thelead branch and the soil pipe, embodying the invention, with parts incross-section; and

Fig. 2 is an enlarged, cross-sectional view taken on line 2-2 of Fig. 1.

Referring now in detail to the drawing, Ill designates a. soil stackmade up of interfltted cast iron pipes including a TY pipe II, having avertical portion I2, and a branch I3 extending to one side, providedwith a usual enlarged hub l4.

Attached to the branch I3 of the TY connection II, is an improvedferrule I5 made of cast brass or the like suitable material. The ferruleI5 comprises a cylindrical wall I6, and outwardly extending annularflanges I! and I 3 at the opposite ends thereof. ferrule I5 is receivedwithin and calked to the hub I4 in the usual manner, as at I9.

One end 20 of a lead branch or bend 2I is inserted within the ferruleI5. The outer diameter of the portion 20 of the branch 2i issubstantially equal to the inner diameter of the One end of the 1cylindrical wall N5 of the ferrule. The portion 28 of the lead bend isbeat against the inner surface of the ferrule in the usual manner.

In accordance with the present invention, bend 2I is attached to theferrule I5 by means of an annular wiped joint 22, extending between theouter surface 23 of the flange I8 and the outer surface of the leadbranch, adjacent said flange. Said outer surface 23 of the flange I8 ofsaid ferrule is first scraped clean and then tinned by the applicationof flux, after which is the annular corner between said outer surface,and the outer surface of the lead branch is filled with solder by wipingthe solder all around, to produce the wiped joint 22.

I-Ieretofore, the usual plumbers brass ferrule has been made with onlyone flange I! inserted into the hub I4, and a wiped joint has been madeby covering the outer cylindrical surface of the ferrule and theadjacent outer surface of the lead branch. Such a wiped joint requiresconsiderable skill and knack, and has been found toconsume considerabletime and use up a relatively large quantity of solder.

In accordance with the present invention there is a considerable savingin time and material, as

the wiped, joint 22 requires less solder and is easier and quicker tomake, and does not require as much solder.

I have found that wiped joints such as disclosed herein, are strong anddurable, and practical and highly eificient, while easy to make.

The lead branch 2| may be connected to the usual annular ring 25, onwhich a bowl is mounted, as shown in Fig. 1 of the drawing.

In Fig. 1 there is shown a ferrule I5 connected to the upper end of thevertical portion of the TY connection in the usual manner, and connected to a lead branch 2l'a by the improved wiped joint 22.

In ferrules now in use, a considerable length of the ferrule must befiled or scraped and tinned by the application of fiux to receive thesolder of the wiped joint. With the present invention, the ferrule maybe made considerably shorter than heretofore by reason of theelemination of the necessity for scraping and tinning the outer surfaceof the cylindriical wall of the ferrule.

The length of the pipe 20 inserted into the ferrule depends upon thelocation of the annular ring 25. If the ring 25 is to be located more tothe left, a greater length of the lead bend 2! is inserted into theferrule.

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is welladapted.

to meet the conditions of practical use.

As various possible embodiments might be made of the above invention,and as. various changes might be made in the embodiment above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying'drawing is to be interpreted as illustrative and not in alimiting sense.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

In combination, a ferrule having a cylindrical wall, and outwardlyextending, annular flanges at the opposite ends of said wall, oneflanged end of said ferrule being adapted to be inserted into the hub ofa soil pipe and calked thereto, a lead pipe having a portion receivedwithin the other end of said ferrule, the outer diameter of said pipebeing substantially equal to the inner diameter of said ferrule. and awiped joint between the outer surface of the flange at said other end ofsaid. ferrule and the outer surface of the portion of the pipe adjacentthereto.

CHARLES PRICE.
